D=tr
r=d/t (I divided the t to the other side)
d=tr
t=d/r (I divided the r to the other side)
Answer:
n ≤ 6
Step-by-step explanation:
2n - 15 ≤ -3
Add 15 to both sides.
2n ≤ 12
Divide both sides by 2.
n ≤ 6
The solution of this inequality is any number less than or equal to 6. There is an infinite number of solutions. Since you are asked to pick two numbers that are solutions, I assume you have choices that were given. Look at the choices, and pick any number less than 6 and 6 itself if it is a choice.
Given:
The linear equation is:
To find:
The statement that best describes the graph of the given linear equation.
Solution:
The slope intercept form of a linear function is:
...(i)
Where, m is the slope anf b is the y-intercept.
We have,
It can be written as:
(ii)
On comparing (i) and (ii), we get
Therefore, the graph has a slope of -1 and a y-intercept of 1. Hence option D is correct.
Answer:
Step-by-step explanation:
In order to find the area of the circle base, we need the radius, and we don't have it. We'll use the volume to find the radius, as follows:
and fill in the givens:
and solve that for r;
so
r = 3.784698783 and plug that in for the radius to find the area of the circle base:
so
gives you that
A = 45 meters squared, exactly. No decimal.
Answer:
A correlation coeff close to +1 would have a positive slope, and all dots representing the data set would be quite close to the regression line.
Correlation is a measure of association between two variables. IF there is a perfect linear association then correlation would be nearer to 1.
Correlation always lies between -1 and +1.
If between-1 and 0 we say there is a negative correlation.
If nearer to 1 than to 0 then we say strong correlation
Here given correlation is 0.95 i.e. positive and have almost perfect linear relation.
Hence we see that Graph C shows almost linear relationship with slope positive
So option C is answer
